The terms piezoelectricity and thermoelectricity refer to the property of certain bodies to polarize themselves electrically (generating a field or an electric potential) under the action of a mechanical (Piezo) or thermal (Thermo) stress.

The piezoelectric or thermoelectric materials are used to meet our growing energy needs. Indeed, they can recover any mechanical energy (vibration, pressure, etc.) or thermal energy by transforming it into electrical energy (or vice versa) for various applications (harvesters, sensors, etc.).

Our strengths

  • Solvent-free production of piezo and thermoelectric materials.
  • Dry and wet deposition of organic and inorganic semiconductors (MeOx).
  • Production of hybrid complex layer stacks based on these materials by thermal sublimation with control of the alignment of the electronic levels.
  • Control of layer doping by co-evaporation.
